Ferrioxamine B
Ferrioxamine B is a bacterial desferrioxamine siderophore produced by actinomycetes. Ferrioxamine B acts as a ligand for FpvB and FoxA, and is transported into Pseudomonas aeruginosa via the FpvB and FoxA transporters. Ferrioxamine B competitively binds to FpvB, thereby antagonizing the uptake of thiostrepton into Pseudomonas aeruginosa. Ferrioxamine B can provide an iron source to support the growth of Pseudomonas aeruginosa under iron-limiting conditions.

Biologische Aktivität
Ferrioxamine B-Fe3+ (1 hour) binds FpvB in P. aeruginosa PA14 ΔfpvA ΔfpvB mutant with two distinct sites (Kd1 = 100 ng/mL, Kd2 = 270,000 ng/mL) and is taken up via a proton motive force-dependent mechanism[1].
Ferrioxamine B (0.0-10 μg/mL) competes with thiostrepton (0.0-17 μg/mL) for binding to FpvB in P. aeruginosa PA14 ΔfpvA ΔfpvB mutant, reducing Thiostrepton (HY-B0990) susceptibility[1].
